ABSTRACT This preliminary report provides the basis for testimony #o be given on April 26, 1988, before the House Appropriation Committee onfInterior, Representative Sidney Yates, Chairman. It was considered important for both the Congress and thefRongelap people to present an overview of the material now available rafher than to wait until all questions have been answered. Meeting the h@aring date has involved some last minute pressures. The final report wil] probably be issued within 2 - 3 months. The chief conclusion is that, based on the estimation of dosage, Rongelap Island may be resettled now. That conclusion} presupposes certain conditions for living which are set out an Adult however, discussed in Section 5 (which may be read without reference tofthe rest of the Report). The chief unsettled point is the dose to infants; it is chrrently under review. Another unsettled point is the transuranic dosage (plutoniun-293, -240, americium-241). It is important to bear in mind that the dosage under distussion is that from continued residence on Rongelap Island from 1978 ( the present), onwards. This adult dosage over the next 30 years is to be no more than 1 to 2% of that experienced from fallout in the Bravo shot. The historical data included in the Report ame interest for general orientation. estimated 1954 from of As referee, I am solely responsible for the contents of this report. However, two consultants have strongly objected to major portYons of it and I am therefore putting their comments together, in their dntirety, in Note 13. For comparison, I suggest that they be read in conj¥nction with Section 5 of the Report (Discussion and Recommendations).
